Abstract

A projection optical system (POS) consisting of a double passed Nd:glass laser amplifier and a phase conjugate mirror (PCM) based on four-wave Mandelstam-Brillouin enhanced mixing is investigated (Fig. 1), A laser pulse (τ = 30 ns) illuminated an object (1) which scattered light isotropicaily. The scattered radiation passed through the beam splitter (2) to the lens (3) and was directed at the amplifier (4) and the PC mirror (5). After being reflected from the PCM the radiation propagated back to the object, while part of the radiation deflected by the beam splitter formed a real image of the object.
